APPARATUS FOR MXNG lVQLASS/ES W'TH STOCK FEED.

Application le. April 21.8, 192g.

This invention relates to apparatus for mixing' dry granular materials oi' stock feed and molasses, and moi'e particularly to a molasses feeder for vertical stock-feed mix- '.ig machine; the vertical mixer being adapted to be used for mixing different kinds of ,fg/'rain or granular materials used for feedy in animals and having' associated-therewith means for feeding` molasses to be mixed with the food materials in the mixing chamber.

lviixing machines have been heretofore provided with means for mixing' molasses with stoel-t feed, and one object of my invention is to provide an apparatus of the character referred to with improved means for feediir molasses for admixtui'e with grain or aranular materials conducted into the mixing' chamber of Ya suitable mixing; device, iireferably` of the vertical mixer type, in such manner as to avoid the formation of lumps as in feed and molasses mixing' machines as here? fore constructed, and to adapt the mixinp; device to be used independently of the means employed for feeding' molasses to be comminpjled with the food-stehQ in the mixing' chau'iber.

ll/luch trouble and inconvenience has been exp 'ienced in cleaning' out the mixing chamber and mixing' devices in what are known in the art as vei'tical mixers as heretot'oi'e ordinarily constructed, on account el the necessarily restricted space `allowed to a 'lord access to the interior of the cham her and the mixing' device employed thereink and another object of my invention is to avoid the trouble and inconvenience inciv dent to cleaning' such mixers, 'by providing a mixing; chamber having' i'emovable panel to afford access to its interior and to the mixing' device therein for the purpose of cleaning the same.

Other objects are to provide a simple and efficient molasses feeding' device that will distribute the molasses upon the n'rain or granular materials within the mixing' chamber in small quantities at different points and to increase the etliciency of such machines and at the same time insure a more perfect mixture of the molasses with other ingredients.

rlhe invention will first be hereinafter more pai'ticularly described, with reference to the accompanying` drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.

Referring te said drawings, in which the same reference letters are used to denote coi'- responding' parts in different views, the letter A denotes a mixing' chamber, which is preferably of cylindrical form, and which is provided at its upper and lower ends with suitable bearings in which is journalcd the shaft of a vertical mixing' device or spiral conveyor ll. said shaft having' on its upper end a gear wheel. C which meshes with a pinion (Z on a driving' shaft ll, on which is secured a gear wheel or pulley E to adapt the shaft to be driven by beltand pulley connection with a suitable motor. rlhe mixing chamber and mixing' device therein are preferably of the construction shown in Patent No. 1,495,807, dated June l0, 1924, illustratiiip; what is known in the art as a vertical mixer; the lower end-portion of the casinar being of frusto-conical form and provided with a .e aule dischargjge opening' or openings controlled b v a slide valve or valves such desired for dischargin thecontents of the mixing` chamber into a spout or receptacle for receiving' the same, and inasmuch as the vertical miner propelI lorms no part of my present invention, which is designed to be used in connection with mixing` devices of' any suitable construction, -further description oi' the vertical mixer appears to be lmneeessary.

lnusing machines for mixin, molasses with stoclelfeed it is iirequently necessary to clean the interior wall or the mixing1 chamber and the mixing' device or devices therein, and to allord access to such chamber it has been the common practice to provide an openinf;` or openings in the vtop thereolf through which access is ali'orded to the interior olf the chamber for the purpose oit cleaning-gy the saine, but this has been found to be inconvenient and troublesome at times, because oit the limited space allowed by such openings for a person of small size to enter the chainber, and to obviate this trouble and inconvenience l provide the mixing chamber v-.fith a removable panel constructed as iiollows,

As shown, a portion oli one side olf the ons ing A is eut away toprovide an oblong` opening', preferably oli rectangular form, in which is litted and removably secured an oblong; panel or closure plate G, which may be of concave-convex form in cross-section to conform to the shape oli the casina, and has edges arranged in alinement with Idie adiacent edges of the Casing around said cut-away portion, so as to prevent the formation of any projection on the interior of the casing; upon which the n'iaterials therein may collect and interlere with the mining operation. @n op posite sides el the openings` are secured vertical metal strips or plates lil of angular torni or provided with apertured .flanges ,o receive fastening` bolts or rivets for securing said plates to the casing` along; the margins of said opening,and similar horizontal plates or strips H1 are secured to the casing' in the same manner, one at the lower end of the opening and another at the upper end thereof; the edges oli said cut-away portion el the casing,- on opposite sides of the opening; and at the upper end thereof being arranged to slightly overlap the angular plates secured thereto, while the angular plate at the lower end of the openingy slightly overlaps the adjacent educ oi the cai-aine; to which it is cured. Vertical and horizontal angular plates l and Il, which are the counterparts of the plates ll and lll, are secured along; 'the edges or marginal portions of the panel G,

so that the plates l slightly overlap the vertical edges olf' the panel,.,while the lower end ot the panel overlaps the lower horizontal. plate l1, 'and the horizontal plate at the upper end oll the panel slightly overlaps said upper end ,I the two vertical plates at each side oli the opening and the two horizontal plates at the upper and lower ends oit the opening` lieing secured together by 'fastening bolts inserted through the outwardly projecliingf;` apertured flanges, thus lirmly securing the panel to the casing; the ov'eriai'iping portions of 'the angular pla t e removable panel seivin.V to l tno joint bepiovides a .ne Vconnection ie panel, the upper end he lightly raised so 'f connection il may be remy., ax fl ood consti uc ie panel or is seemed ni place so as i i ect ,to loira an mi .c n i' a i integral part or the nin chamber oi cas ing; 'and provide a smooth interior surface that will not obstruct the downward ol the material alone' tno rior wall oit the easing' or cause the i f interior wall ani conseque'.l the ellectual n' i' molasses to he coi, .nii y'itin For convenience in reniov. rei)lac-iria the panel, it may be provided wi 'h one or more handles g on the out si'lc t i' if, as shown. The top or cover or' the mixing' chamber has formed thereon or secur al thereto, on the underside thereof, a 'depending` annular tlangge 7c into which protrudes ie upper endportion of a molasses cup or container L, secured on the vertical shalt so to revolve therewith. lhe bottom oit' said cup is fo ined or provided with a centrally disposedV tubular huir 1e portion ,Vthrouggh which the vertical shalt passes, and a set screw Z1 serves to secure the cup upon the shalt with provision ttor vertical adjustment ln the form shown the y lar inner and outer upright members Z2 and Z3, which are preferably liormed integrally with the iniperfora'te bottoni and are spaced apart so as to previ de an annular trough or liquid container. 'lo prevent any liquid in the cupplrorii rising; high enough to overflow the inner annular member, the latter eX- tends up around the stallingbox M dependingl from the under side of the rop el 'the mixing' chamber in which the vertical shaft is journaled at the top et the chamber. rlihe molasses cup or container li is in communica tien with a source of supply vthrough pipe N having its delivery end protrudin through the upper end of the inning; chamber and an aperture in the depending flange 7c for discharging molasses directly into the annular space between the annular upright meinM bers of the container, to which is secured a discharge tube or nozzle, or a plura cup consists of annu-V YKals and the quantities at diii'erent points at different distances from the vertical shaft and the inner wall of the mixing chamber. As shown in Figs. t and 5, the molasses cup is provided with a single distributing tube or nozzle, but two or more tubes or nozzles may be provided, as desired, and toprevent the liquid from being thrown out against the interior wall of the casing or mixing chamber by centrifugal force as the container revolves the distributing tube may have its outer end closed, as

shown in Fig. 5, or turned downwardly as.

hereinafter described.

In Figs. 6 and 7 of the drawings is shown a modification of the distributing means. ln this instance the molasses cup L1 is provided with a plurality of discharge tubes or nozzles P of different lengths having their free ends turned downwardly to prevent the liquid from being thrown against the interior wall of the casing by centrifugal force.l The discharge tubes or nozzles P, as shown, increase in length around the container; a short nozzle P being provided at one side of the cup, and longer nozzles P1, P2 and P3 arranged at equi-distances apart around the container and increasing in length in the order mentioned.

As will be seen, an unobstructed annular space is provided around the spiral conveyor, which is adapted to produce an upwardly moving column of material surrounding the conveyor and overturn and throw the same off into said annular space at the upper end of the conveyor, from which point the mixture is caused to descend by gravity through said annular space until it reaches the lower end of the conveyor when the material will be again raised centrally of the descending current and so on, thus overturning, agitating and mixing the materials until a thorough mixture is effected, whereupon the contents of the chamber may be discharged through a valve controlled discharge opening at the foot of the vertical shaft.

ln operation, the dry materials to be mixed are placed in or conducted into the mixing chamber and mixed in the usual way by imparting motion to the mixing device within said chamber, either with or without the addition of molasses as an ingredient of the mixture, and when the desired mixture is effected the contents of the mixing chamber may be emptied into a suitable receptacle or, conducted into a discharge spout at the lower end of the mixing chamber; the materials being mixed in batches of greater or less quantity and discharged from time to time as desired. lWhen molasses is to be mixed with the soft dry feeds or grain or granular material, a valve in the feed pipe N, which is connected with a source of supply, is opened, and molasses, preferably heated so as to adapt it to run freely and prevent cold molasses from adhering to the feed pipe and distributing means within the mixing chamber, is conducted into the revolving molasses cup and distributed as the cup revolves within the mixing chamber; the molasses being caused to flow by gravity when the heating chamber is located above the mixing chamber, or a pump (not shown) may be employed, when the source of supply is located below the mixing chan'iber'.
